l SPECIFICATION forming part of Letters Patent No. 731,863, dated June 23, `1903,

Application filed November 15, 1962. Serial No. 131,541. (No model.)

.To all whom it 71mg/ concern:

Be it known that I, JOHN J. COOKE, a citi-` Zen of the United States, residing at Cherry Valley, in the county ofOtsego and State of New York, haveinvented new and useful Improvements in Treadle-Powers, of which the,

following is a specification.

My invention has relation to improvements in treadle-powers; and the object is to provide an improved and simplified mechanism of the kind named and for the purposes where sucli mechanism may be advantageously used.

The invention embodies a support, a treadle, a spring to lift the treadle, a crank having one arm longer than the other, a connection between the crank and the treadle, a rod sldingly connected to the longer arm of the crank, and a bracket slidinglyand adjustt ably secured to said rod and adapted to be connected to a revoluble member, all as hereinafter fully described and the novelty thereof particularly pointed out and distinctly claimed.

It will be premised that while I have illustrated the device as operatively connected to a cream-separator it is apparent that it may with equal adaptability be utilized whenever a reciprocating movement is lused to produce arotary motion.`

i I have fully and clearly illustrated my invention in the accompanying drawings, forming a part of this specification, and wherein- Figure l is a perspective View of the complete device, showing it as associated with a cream-separator. Fig. 2 is a side view of the bracket by which the reciprocating pitrnan is supported. Fig. 3 isa perspective viewshowing a double crank, used as the operating means.

In the drawings like reference notations appearingin the differeutillustrations denote e the same parts. l

Aso

Referring to the drawings, A designates a cream-separator of any selected and approved make having a rotary shaft, the end of which is projected from the casing, as shown. l designates a double-inclined supportingbench, in the apex of which is formed a bearing-sleeve 2, wherein is pivotally posited a crank-shaft 3, to the free end of the arm of which is pivotally connected the upper end of the treadle pitman or rod 4. To the base the crank-shaft is secured an arm S, made longer than the crank-arm and formed with an elongated slot 9, wherein a wrist-pin 10 is slidingly secured. To the pin 10 is `pivotally secured the lower end of a pitman-rodl 11, the upper end portion of which is slidably and adjustably arranged in a sleeve or passage in a bracket l2, substantially as shown in the drawings. A set-screw 13 is provided to hold the bracket in any position to which it may he placed on the pitman. The bracket 12 is formed with an Overhanging ear 14 and a pivotally-supported ,jaw l5, having a perforated and threaded lug 16, which takes in a clamping-screw 17, passed through a lug 18 on the end of the arm l-L, whereby the bracket may be clamped to the handle 19 of the crankarm of the cream-separator, substantially as shown in the drawings.

In Fig. 3 of the drawings is illustrated the device provided with a double crank-shaft a and treadles b c, supported on the wrists of the cranks, as shown. In other respects the construction is identical with that of Fig. l. The operation is readily ascertained from the foregoing description, taken in connection with the drawings. Upon operating the treadle the crank, with the arm 8 and the pitlnan 11, is reciprocated and the arm 19 re- Volved.

Having thus fully described the invention, what is claimed as new isl.V A trcadle-power, comprising a doubleinclined supportingbench formedfwith a bearing in its apex, a treadle pivotally mounted to one of the legsof the bench, a crank journaled in the bearing in `theapex of the bench, a connecting-rod pivotally secured to the free end of the crank-arm and its other end secured to the treadle, a spring to lift the treadle,l an arm longer than the crank rigidlysecured to the crank-shaft and formed IOO with an elongated slot in its outer portion, and a rod having its lower endslidingly secured in the said slot and its upper end adjustably secured to a rotatable member.

2.. A treadle-power, comprising a double? rigidly secured to the crank-shaft and formed with an elongated slot in its outer portion, a

rod having its lower end slidingly secured in the said slot, a bracket adj ustably secured to the upper end of said rod, and a revoluble member adjustably projected and-secured in the bracket.

In testimony whereof I afx my signature in presence of two Witnesses.
